Application filed February 18, 1926. Serial No; 89,131. V

This invention relates to a novel wrench for twisting a wire splicing sleeve andthe ends of the wires encased by the sleeve,and has for one of itsobjects to provide a strong, durable and simple wrench of this character. that can be operat'edwith'the least possible interference from the block and fall-used to hold the wires during the splicing operation.

,lVith the foregoing and other obje ts in view, the invention consistsof the novelconstruction, combination and arrangement of parts hereinafter fully described and claimed, and illustrated-Vin the accompanying drawing, whereinr r Figurel is a view-in side elevation-ofthe wrench with the jaws thereof closed,

Figure 2 is a similar .view with the jaws partly opened,

Figure 3 1s a sectional view taken on the plane indicated by the line 3-3 of Figure 1 v Figure '4 is a similar view taken on the plane indicated by the line 44 of Figurel and v Figure 5 is a detail view illustrating the manner in which the sleeve receiving dies are secured to the jaws of the wrench.

Corresponding and like parts are referred to in the following description, and designated in the several views of the accompanying drawing, by similar reference characters. p 7

The wrench comprises similar aws 2 and 3 which are preferably of elongated rectangular formation and are assembled with their longitudinal edges 4 and 5, respectively, in opposition. Lugs 6 are formed on the jaw 2 adjacent an end thereof and project inv wardly beyond the inner edge 4 of the jaw,

and lugs 7 are formed upon the jaw 3 adjacent the corresponding end of this jaw and extend inwardly beyond the inner edge 5 thereof. The lugs'r6 and 7 are of semicircular formation and the lugs of one jaw tit in'semi-circular recesses in the other. A bolt 8 passing through the lugs 6 and 7 pivotally connects the jaws 2 and 3. A semicircular lug 9 extends from the inner edge 5 of the jaw 3 and occupies when the jaws are closed'a recess 10 in the jaw 2 and, opening out through the inner edge 4 thereof. The lugs 6 and 7 and the lug 9 are adapted to prevent the jaws 2 and 3 from having'any relative twisting movement when they are closed and the wrench is in use. Thefree end edge of the jaw 82 is provided with a T-shaped recess llfor the reception of a correspondingly formed dog '12 pivoted as at 13 to the jaw 3. The free end edge of the jaw 3 is provided with a recess 14-for the receptionofthe dog 12 and'said jaw is provided with a recess 15 for the reception ofa sprlng 15 which bears against one end of the dog-12 to yieldingly hold it in active position. The other end of the dog 12 projects beyondthe' inner edge 53ofthe jaw'3, and it is this end that occupies the recess 11 incthecjaw 2. Theends of thechead 12 of the dog 12project beyond the sides of-the jaw 2 -.to provide finger grips by means of which the dog-may. be: retraetedwhen it is desired to open the jaws 2 and 3 orclose the same. i

The jaws 2and 3 are providedcentrally between their ends with dies ldfor the reception :Of, the splicing sleeve. The dies extendin opposite directions beyond the jaws 2 and 3, and are removably secured by screws 16 in openings 17 formed in the jaws and extend through the sides and inner edges thereof. Lugs 18 carried by the dies 16 and occupying recesses 19 formed in the jaws 2 and 3 and communicating with the openings 17, hold the dies against movement laterally with respect to the jaws. i

Cylindrical passages 20 are formed in the jaws 2 and 3. These passages are located adjacent the outerside edges of the jaws 2 and 3 and are arranged in parallel relation to said edges and open out through the end edges of the jaws Bayonet slots 21 are formed in the jaws 2 and 3 and 001m municatei with the passages 20 and open out through the end edges of the jaws.

Handle bars 22 are slidably mounted in the passages 20 and are provided with enlarged terminals 23 adapted to prevent them from becoming accidentally detached from the jaws 2 and 3. The handle bars 22 may be 1 adjusted to extend in Opposite directions beyond the end edges of the jaws 2 and 3, as shown in Fi ure 1, or adjusted to extend beyond the free end edges of the jaws as shown in Figure 2, and are adapted to be locked in adjusted position by pins 24 cari ried by them adjacent their ends and adapted to be 'removably engaged with the bayonet slots 21.

In practice, when it is desired to apply the wrench to a sleeve mounted on the ends of the wires to be spliced,'the handle bars 22 are-adjusted to eXtend beyond the free end edges of the jaws 2 and 3, and thereafter the dog 12 is retracted to permit the jaws to be swung into opened position.

The wrench is then applied to the sleeve and the jaws 2 and 3 swung into closed position by the handle bars 22 and locked inthis position by the dog 12. The-wrench is now turned to twist the sleeve and the ends of the wires, and during this operation. the

fall by which the wires are held.

handle bars 22 are alternately adjusted to project beyond opposite end edges of the jaws 2 and 3 so as to clear the block and As the dies 16 are removably secured to the jaws 2 and 3, the wrench can be equipped with dies having active faces of the size necessary to effectively twist the sleeve used.

It should be understood that the drawing is'merely illustrative and does not pretend to give exact proportions. Furthermore, the said drawing is illustrative of a preferred construction, it being our expectation that various changes and modifications may be made without departing from the "spirit and scope of the invention.

l/Vhat is claimed is 1. A wrench of the character set forth, comprising jaws, handle bars, and means adjustably connecting the 'handle bars to the jaws to permit the handle bars to be extended in the same or in opposite directions beyond the jaws.

2. A wrench of the character set forth,

comprising jaws, handle bars, means adjustably connecting the handle bars to the jaws to permit the handle bars to be extended in the same or in opposite directions beyond the jaws, and means adapted tosecure the handle bars in adjusted position with respect to the jaws.

3. A wrench of the character set forth, comprising pivotally connected jaws providedwith passages arranged at right angles to their pivots, and handle bars adjustably mounted in the passages to permit them to be extended in the same or in opposite di- I). p V

with the slots to secure the handle bars 5? against casual movement with respectito the jaws. v y In testimony whereof we affix our signatures.
